This report describes the Utrecht regio with regard to sustainability and circular business models.
Property sharing is one of the most prominent examples of the rapidly expanding sharing economy. Travelers around the world often opt to stay at a stranger's apartment instead of any other tourism accommodation. Trust is essential in this choice, because staying with, or taking in, strangers can entail great risks. To create trust between users, sharing platforms often promote a sense of community. However, the relation between sense of community and trust in the sharing economy is still largely unknown. To investigate this relation, both hosts and guests of two sharing platforms, namely Airbnb and SabbaticalHomes, were surveyed. The findings indicate that sense of community indeed enhances trust between users. Moreover, the evidence suggests that hosts have a stronger sense of community than guests. Also, a significantly higher sense of community was found on the platform where identification between users is higher. This study shows that affect for the community contributes to the understanding of trust in the sharing economy.
What will a shopping street look like in 2025, when online shopping continues to show double-digit growth? And what will 3D printing do to factories and logistic companies, when we can ‘print’ more and more products at home or around the corner?The digital economy is one of the most pervasive game changers in cities. It creates and destroys, and affects the way cities function in many ways. But what is exactly the digital economy about? How big is it? Which types of transformation is it provoking in urban economies? And, importantly, what can local governments do to cope with the digital transition and foster sustainable urban development?

The transition towards an economy of wellbeing is complex, systemic, dynamic and uncertain. Individuals and organizations struggle to connect with and embrace their changing context. They need to create a mindset for the emergence of a culture of economic well-being. This requires a paradigm shift in the way reality is constructed. This emergence begins with the mindset of each individual, starting bottom-up. A mindset of economic well-being is built using agency, freedom, and responsibility to understand personal values, the multi-identity self, the mental models, and the individual context. A culture is created by waving individual mindsets together and allowing shared values, and new stories for their joint context to emerge. It is from this place of connection with the self and the other, that individuals' intrinsic motivation to act is found to engage in the transitions towards an economy of well-being. This project explores this theoretical framework further. Businesses play a key role in the transition toward an economy of well-being; they are instrumental in generating multiple types of value and redefining growth. They are key in the creation of the resilient world needed to respond to the complex and uncertain of our era. Varta-Valorisatielab, De-Kleine-Aarde, and Het Groene Brein are frontrunner organizations that understand their impact and influence. They are making bold strategic choices to lead their organizations towards an economy of well-being. Unfortunately, they often experience resistance from stakeholders. To address this resistance, the consortium in the proposal seeks to answer the research question: How can individuals who connect with their multi-identity-self, (via personal values, mental models, and personal context) develop a mindset of well-being that enables them to better connect with their stakeholders (the other) and together address the transitional needs of their collective context for the emergence of a culture of the economy of wellbeing?
Onze huidige voedselvoorziening wordt gekenmerkt door overmatig gebruik van bestrijdingsmiddelen zoals antibiotica, genetische manipulatie, overdadig veel transport, water en andere grondstoffen worden gebruikt en productieprocessen gebaseerd op fossiele brandstoffen. Ook wordt veel landbouwgrond dusdanig uitgeput dat de kwaliteit van de grond en de diversiteit sterk achteruit gaan. Gezonde en duurzaam geproduceerde voeding zou voor iedereen bereikbaar moeten zijn. Bovendien is er veel leegstand in verschillende regio’s, deze leegstand kan door middel van aquacultuur systemen zeer waardevol worden benut. Dit is de aanleiding geweest om te zoeken naar alternatieve mogelijkheden voor duurzame productie van voedsel binnen de agrifoodsector. Geïntegreerde aquacultuur systemen worden verwacht goed toepasbaar te zijn voor duurzame voedingsproductie. Deze systemen verminderen de afhankelijkheid van de huidige voedselvoorziening van chemie, olie en gas. Bovendien stimuleert het de lokale en regionale economie en schept het duurzame werkgelegenheid. De doelstelling is het sluiten van de materiaalstroomketen, het voorkomen van afvalstoffen en het stimuleren van grondstof besparing. De aanpak van dit project is daarom gericht op de transitie naar circulaire materiaalstromen waarbij hoogwaardig hergebruik van de materialen mogelijk is op een manier waarbij waarde wordt toegevoegd. Hierbij worden mogelijkheden verkent in het kader van de biobased economy en nieuwe business- en verdienmodellen van dergelijke geïntegreerde aquaculturen. De onderzoeksvraag voor A2FISH is welke circulaire business- en verdienmodellen er realiseerbaar zijn voor kansrijke geïntegreerde aquacultuursystemen binnen de agrifoodsector. Om die onderzoeksvraag uiteindelijk te kunnen beantwoorden, zijn een aantal deelvragen geformuleerd: • Welke aquacultuursystemen zijn kansrijk toepasbaar binnen de agrifoodsector? • Aan welke technische en economische aspecten moet een aquacultuursysteem voldoen om te komen tot kansrijke business- en verdienmodellen? • Welke soorten planten kunnen worden met waardevolle inhoudsstoffen kunnen worden gekweekt met de aquacultuursystemen? • Welke soorten gangbaar industrieel visvoer kan worden gefabriceerd uit reststromen uit de voedingsmiddelenindustrie en welke invloed heeft dit voer als bemesting op de waterkwaliteit? • Hoe ziet een vervolgtraject voor een geïntegreerd circulair aquacultuursysteem eruit en in hoeverre is dit anders dan voor gangbare alternatieven?
Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.
